Definitions

  • the present invention relates to a connecting terminal.
  • the insulating housing and push button of conventional connecting terminals may be made of plastic material.
  • the forces acting on the push button and also the insulating housing can cause the plastic material to deform. This is especially true because the space available in the area of the clamping spring for accommodating the conductor insertion opening and the push button next to the clamping spring, and thus the available material thickness, is very limited.
  • a connecting terminal having an insulating housing, comprising a conductor insertion channel extending toward a conductor insertion axis with an at least partially circumferential conductor channel wall arranged coaxially to the conductor insertion axis, and an actuation channel disposed next to the conductor insertion channel, a leg spring bent in a U-shape having a contact leg, a clamping leg and a spring bow connecting the contact leg to the clamping leg, a bus bar and a push button received in the actuation channel in a longitudinally displaceable manner.
  • the contact leg is mounted on the bus bar and a clamping edge of the clamping leg forms a spring clamp connection with a contact region of the bus bar for clamping an electrical conductor inserted in the conductor insertion channel.
  • Coaxial is not only meant to be the arrangement in reference to a cylindrical conductor channel wall. When the center of gravity of a constant cross section of the conductor channel wall in the extension direction runs parallel to the conductor insertion axis, then it is also coaxial.
  • the orientation of the actuation axis which is defined by the longitudinal displacement direction of the push button in the actuation channel, relative to the conductor insertion axis at an angle of 5° to 30° and preferably 5° to 20°, it is ensured that the conductor insertion opening and the push button can be received in a very small space.
  • the inserted conductor and the push button are thereby displaced toward one another to a common (virtual) meeting point into the insulating housing when they are at such an acute angle to one another.
  • the angular offset allows for the space between the actuation channel and the conductor insertion channel thus made available to be used to optimize the support for the push button.
  • the direction of force acting on the push button by the clamping leg of the clamping spring can be improved in order to prevent the push button and thus also the insulating housing from deforming.
  • the angle can in particular be formed larger while being in the angular range of more than 20° specified above. Comparable structural designs are conceivable in order to obtain the desired angular orientation.
  • the conductor channel wall may form a dividing wall to the actuation channel.
  • the push button is then guided in a section of the dividing wall which conically tapers the conductor insertion channel. This section can be oriented in parallel with the actuation axis.
  • the actuation axis can be approximately perpendicular to the plane spanned by the connection opening. “Approximately perpendicular” can be understood to mean in particular an angle of 90° with a tolerance of ⁇ several degrees, for example, ⁇ 5° and preferably ⁇ 2°.
  • This conically tapering section is not only used in this way for the targeted guidance of a stripped end of an electrical conductor to be clamped to the clamping point, but also provides a support wall for the push button in the area located close to the clamping spring. Under the influence of the deflected clamping spring, the force components acting via the push button on the conically rejuvenating section of the dividing wall act at a more acute angle than if the push button were to be supported on a non-conically tapering section of the dividing wall of the conductor insertion channel. In this way, the risk of plastic or elastic deformation to the dividing wall can be reduced.
  • the bus bar can have a connection opening, wherein the leg spring is inserted into this connection opening.
  • the push button In the state of actuation, in which the clamping leg is displaced by the push button toward the contact leg, the push button then projects out into this connection opening.
  • connection opening which may also be designed like a channel in the manner of a material passage with guide walls, an electrical conductor can be reliably guided to the clamping point. This is especially true for stranded electrical conductors whose strands can otherwise spread open when the conductor is clamped with the aid of the push button without previously deflecting the clamping spring.
  • the available space for receiving the electrical conductor and the clamping spring is greatly reduced. Optimal utilization of the available small space succeeds without risk of deformation by orientating the actuation axis and the conductor insertion axis at an angle of 5° to 20° to each other.
  • the interaction of the push button and the clamping spring is significantly improved if the displacement of the push button is taken advantage of as much as possible towards the clamping end of the clamping leg. This succeeds if the push button dips into the connection opening in the state of actuation. Thereby, the available space is further restricted. In fact, however, this displacement is available when the actuation axis and the conductor insertion axis are oriented towards each other at an angle of 5° to 20°. This way, the electrical conductor is advantageously guided along the push button and does not encounter the clamping leg.
  • the push button can have a shoulder which reduces the width of the actuation end.
  • the shoulder then forms a stop for resting on a peripheral region of the bus bar which delimits the connection opening. Due to the fact that the actuation end of the push button tapers off in order to dip into the connection opening, the displacement path of the push button is delimited by means of the shoulder, which forms a stop between the push button and the bus bar.
  • the push button is formed wider above the actuation end than within the actuation end. This way, the push button is more stable and can be supported at the widened end of the insulating housing in an area that, due to the cylindrical design of the adjacent conductor insertion channel, is stronger than in the central section.
  • the surface of the push button which faces towards the clamping leg can be formed from the actuation head to the clamping leg without a projection.
  • the push button is formed free of projections toward the clamping leg, in cross section perpendicular to the actuation axis when viewed starting from an actuation head in the direction from the conductor insertion channel to the clamping spring. If the actuation end thus has a cross section which is constant in the direction of the clamping leg or in the opposite direction towards the mouth of the conductor insertion channel, i.e., which has no projection, then possible bending moments are avoided or at least reduced, which can act on the push button by the clamping spring. In addition, the space required by the push button is kept to a minimum with the projection-free design.
  • the end face of the actuation end of the push button acting on the clamping leg may have a rounded contour. In that case, the actuation end tapers, but because of the rounded contour, no adverse projection is formed.
  • the actuation channel In a head section, which is located next to a cylindrical sheath receiving section of the conductor insertion channel, the actuation channel can be conically widened toward the outside of the insulating housing.
  • the push button has an actuation head in the conically widened head section, which viewed from the conductor insertion channel to the clamping spring increases in thickness towards the outer side of the insulating housing.
  • the space towards the outside which is increased due to the oblique position of the actuation axis and the conductor insertion axis, as compared to a parallel alignment, can be used to realize a widened actuation head.
  • the actuation channel then has a cross section that is matched to the conically widening head section, by means of which demolding of the injection mold in the injection molding process of the insulating housing is easily and reliably possible.
  • a surface for exerting pressure on the push button is provided, which can be reliably acted upon using commercially available screwdrivers as an actuation tool.
  • the clamping leg of the clamping spring can be aligned such with respect to the spring bow that the clamping leg extends next to the push button in the direction of extension of the push button and after a deflection, is guided through the actuation channel and the conductor insertion channel or their openings below the actuation end of the non-actuated push button in its resting position.
  • This deflection of the clamping leg behind which, when viewed starting from the spring bow, the clamping leg is guided under the actuation end of the push button, represents the range in which the distance between the clamping leg and the contact leg is the least.
  • the actuation end of the push button is then aligned such to the clamping leg that the actuation end biases the section of the clamping leg located behind the deflection and upon displacement of the push button slides along said section.
  • the clamping spring is biased at a distance from the spring bow in the area of the clamping leg starting from the spring bow located behind the deflection. This ensures that the force effect of the clamping spring with respect to the sliding plane of the push button is at such an optimum angle on the insulating housing or in the direction of the actuation axis that the tilting and bending moments and deformation energy acting on the push button are kept as low as possible.
  • the deflection of the clamping leg may have an internal angle in the range of 90° to 160°, and preferably up to 140°. This ensures that according to the reasons mentioned above, the clamping leg is oriented at a suitable proportion to the actuation axis or to the sliding plane of the push button.
  • the clamping leg can form the clamping edge on the clamping leg end with its end edge.
  • a clamping section adjoining the clamping leg end at the clamping edge can be bent pointing towards the connection opening of the bus bar.
  • the clamping leg of the clamping spring can be formed such that in every state of actuation, it exerts a force on the push button at an angle of less than 50° to a sliding plane, on which the push button is guided longitudinally displaceably. This ensures that tilting moments acting on the push button as well as deformation energy are kept as low as possible.
  • the actuation axis and the conductor insertion axis can intersect the clamping leg of the clamping spring independently of each other at different intersections and may run mutually spaced through a connection opening in the bus bar to intersect only just below the plane of the bus bar, which contains the connection opening.
  • the push button and the conductor to be clamped are close to each other and are aligned at an angle to each other, such that the push button and the electrical conductor act on the clamping leg independently of one another, wherein upon actuation, the push button slides along the clamping leg.
  • the actuation end of the push button can be close to the clamping leg end or close to the clamping edge, such that the connection can be overall reduced.
  • the actuation forces can be homogenized and thus overall reduced.
  • the actuation force can thus be kept mostly constant over the entire actuation path, which leads to a consistent level of the actuation force. This also makes it possible to securely and consistently return the push button.
  • the push button may have a shoulder which with a projection in the actuation channel forms a return stop in the direction counter to the actuation direction of the push button. This prevents the push button from falling out of the actuation channel.
  • the push button is introduced in the actuation channel, wherein the side walls can widen until the return stop catches behind the recess or the latching edge of the side wall.
  • the boundary wall of the actuation channel situated opposite the dividing wall is inclined relative to the actuation axis.
  • the inside wall of the actuation channel opposite the dividing wall is designed to be inclined towards the actuation opening of the actuation channel in the direction of the dividing wall.
  • the push buttons may have groove-like depressions. This groove-like depressions can be arranged, for example, on the lateral bearing surfaces. For different types of push buttons, different depressions can be provided. This way, it is possible to encode the push buttons for optical sensing in automated assembly.
  • the center of the connection opening in the plane of the bus bar thus does not align with the center of the actuation channel, so that when the push button is inserted and overall symmetrically designed, a gap is present in the actuation channel between the lateral wall of the insulating housing of the connecting terminal and the push button.
  • the actuation head of the push button is formed slightly thicker in the width direction than in the rest of the section. This results in the actuation opening of the actuation channel being filled in as much as possible in the width direction except for a small gap.
  • the push button is aligned slightly tilted in the actuation channel in the series-line up direction of the terminal block on a mounting rail.

  • the insulating housing 2 has a conductor insertion channel 3 which is delimited by circumferential conductor channel walls 4 .
  • An actuation channel 5 is arranged next to the conductor insertion channel 3 in which a push button 6 is displaceably mounted.
  • the conductor channel wall 4 of the conductor insertion channel adjoining the actuation channel 5 forms a dividing wall 7 to the actuation channel 5 .
  • the connecting terminal 1 further has a bus bar 8 with a connection opening 9 , which is introduced into the plane which is spanned by the bus bar 8 .
  • the connection opening 9 is formed as a material passage having lateral guide walls 10 a that project downward from the plane of the bus bar 8 in the insertion direction of an electrical conductor and are oriented in the longitudinal direction of the bus bar 8 , as well as a bearing wall 10 b and a clamping wall 10 c .
  • the guide walls 10 a are integrally formed from the material of the bus bar 8 and provide guide walls for an electrical conductor.
  • a leg spring 11 bent in a U-shape is inserted into this connection opening 9 of the bus bar 8 .
  • the leg spring 11 has a contact leg 12 which rests against a bearing wall 10 b projecting from the bus bar 8 and is supported there.
  • a spring bow 13 adjoins the contact leg 12 of the leg spring 11 .
  • the leg spring is received in a free space of the insulating housing 2 .
  • the range of motion of the leg spring 11 may be limited by the wall surfaces of the insulating housing 2 restricting the free space, and optionally by an additional holding pin 14 .
  • This clamping leg 15 dives with its free connecting terminal end into the connection opening 9 .
  • the clamping leg 15 forms a clamping edge 17 on the clamping leg end 16 with its end edge.
  • An electrical conductor introduced in the conductor insertion channel 3 can then be clamped between the clamping edge 17 and the bus bar 8 .
  • the bus bar 8 provides a clamping wall 10 c which is integrally formed from the material of the bus bar 8 and extends obliquely to the plane of the bus bar 8 into the alignment of the connection opening 9 .
  • This clamping wall 10 c is formed by a bending contour such that a projecting contact edge 19 is provided and, in the illustrated state of rest, the clamping edge 17 abuts the connection opening 9 of the clamping wall 18 without the conductor being inserted.
  • the clamping leg 15 In the vicinity of the spring bow 13 , the clamping leg 15 has a deflection 20 and is guided such that in the illustrated non-actuated state in which the clamping leg 15 is not deflected by the push button 6 , the clamping leg 15 extends starting from the spring bow 13 , initially in the direction of extension of the push button 6 next to the push button 6 and at the deflection 20 ultimately below the actuation end 21 of the push button 6 .
  • the clamping leg 15 is transversely guided in this way through the actuation channel 5 and the conductor insertion channel 3 , i.e., through the mouths thereof. “Transverse” is understood to mean that the clamping leg 15 intersects with the actuation channel 5 and the conductor insertion channel 3 at an angle of more than 45° and is thus aligned substantially perpendicular thereto.
  • the clamping leg 15 is further formed with its deflection 20 such that the distance between clamping leg 15 and contact leg 12 is the smallest at the deflection.
  • the dividing wall 7 is formed down to the clamping leg 15 .
  • the dividing wall 7 does not have to touch the clamping leg 15 , but instead can adjoin it at a distance of a small gap.
  • this distance should be as small as possible and preferably less than the thickness of the clamping leg 15 as a threshold for tolerance. It is thus achieved that also in the vicinity of the clamping spring 11 , the push button 6 is guided in a region in which the force action by the clamping spring 11 on the push button 6 and thus on the adjoining dividing wall 7 is the greatest.
  • a cylindrical sheath receiving section M is created by the circumferential conductor channel walls 4 .
  • This sheath receiving section M can also be oval or polygonal. It is only essential that in the area of the sheath receiving section M, the diameter or the cross sectional area over the conductor insertion axis L is constant.
  • the conductor insertion axis L is determined by the direction of extension of the conductor insertion channel 3 and thus by the conductor channel walls 4 centrally extending thereto.
  • the dividing wall 7 serving as a partition to the actuation channel 5 extends in the direction of the actuation axis B and is aligned in parallel with said actuation axis B.
  • the actuation axis B is determined by the direction of extension of the push button 6 and by the shape of the interior walls of the actuation channel 5 adapted thereto, which run concentrically around the actuation axis B.
  • actuation axis B is aligned at an angle to the conductor insertion axis L.
  • the angle between the actuation axis B and the conductor insertion axis L is in the range of 5° to 20°. In the illustrated embodiment, it is approximately 15°+/ ⁇ 5°.
  • actuation axis B is aligned approximately perpendicular to the plane of the bus bar 8 and thus to the plane which is spanned by the connection opening 9 .
  • the conductor insertion axis L is at an inner angle of about 75° to the plane of the bus bar 8 .
  • the actuation channel 5 is widened conically towards the outside of the insulating housing 2 .
  • the actuation head 22 of the push button 6 increases in thickness towards the top end when viewed in cross section from the conductor insertion channel 3 to the clamping spring, i.e., in the illustrated section.
  • an actuation slot 23 or other recess which is provided for receiving the end of an actuation tool.
  • the dividing wall 7 between the conductor insertion channel 3 and the actuation channel 5 has a lobe 24 at its outer end.
  • the latter is formed by elastic deformation after demolding an injection molding tool part from the conductor insertion channel 3 and the actuation channel 5 .
  • FIG. 2 shows the connecting terminal 1 of FIG. 1 in the now actuated state. It is evident that now, the push button 6 is shifted linearly in the actuation channel 5 in the direction of the actuation axis B down toward the bus bar 8 . In this case, the push button 6 is guided along a sliding plane G formed by the dividing wall 7 in the direction of the actuation axis B.
  • the clamping leg 15 of the clamping spring 11 exerts a force on the push button 6 .
  • the force direction is always less than 50° to the sliding plane G and thus directed substantially in the direction of the actuation axis B.
  • the clamping leg 15 is shown in two deflection states. In the upper state overlapping the push button 6 , the push button 6 would not dip into the connection opening 9 of the bus bar 8 . In this case, the mating dimension S 1 for clamping an electrical conductor would be much lower than the smallest diameter of the conically tapering conductor insertion channel 3 . An electrical conductor would then encounter the connecting terminal end 16 and be guided by the latter into this bottleneck.
  • the actual deflection state of the clamping leg 15 is the one deflected further having the mating dimension S 2 . It becomes apparent that here, a mating dimension is achieved that almost corresponds to the entire smallest diameter of the conically tapering conductor insertion channel 3 .
  • the push button 6 dips with its actuation end 21 into the connection opening 9 of the bus bar 8 with a depth T. This depth T is greater than the thickness of the bus bar 8 in the area adjoining the connection opening 9 . It becomes evident that an electrical conductor guided by the dividing wall 7 , which is inserted into the conductor insertion channel 3 , is subsequently first guided through the actuation end 21 of the push button 6 to then first reach the clamping edge 17 .
  • the actuation end 21 of the push button 6 thus lies between the free end of the dividing wall 7 facing the inside of the connecting terminal and the clamping leg end 16 .
  • the clamping edge 17 of the clamping leg 15 is thus recessed from the actuation end 21 of the push button 6 .
  • connection opening 9 for clamping the electrical conductor and for receiving the clamping spring 11 may continue to be utilized to accommodate the push button 6 by the angular offset of actuation axis B and conductor insertion axis L. This way, it is possible in the completely actuated state to act on the clamping spring 11 at a point as far away from the spring bow 13 as possible, thereby optimizing the force effects.
  • the actuation head 22 conically widening towards the outside has adapted to the head portion of the actuation channel 5 , which conically widens towards the outside of the insulating housing 2 .
  • an optional step 25 at the head portion together with a step 26 in the actuation channel 5 can form a stop, by means of which the displacement of the push button 6 to the bus bar 8 is delimited.
  • FIG. 3 displays a plan view of a section of the connecting terminal 1 from FIG. 1 in the non-actuated state. It is evident that the head portion 22 has an actuation slot 23 . This can also be a different shape, such as cross-shaped, square or round.
  • the dividing wall 7 forming a conductor channel wall 4 is curved between the conductor insertion channel 3 and the actuation channel 5 when viewed in the cross section of the conductor insertion channel 3 .
  • the actuation head 22 has a curved contour adapted thereto. This also applies to the section of the push button 6 adjoining the actuation head 22 and leading towards the actuation end 21 , which thus has a constant cross section over its length.
  • FIG. 4 shows a cross sectional view of the connecting terminal 1 of FIG. 1 in the non-actuated state as a cutout.
  • the push button 6 has a smaller width than in a central portion 27 adjoining thereto and leading towards the bus bar 8 .
  • bearing surfaces 28 a , 28 b laterally project from the contour of the push button 6 , which are supported on guide wall surfaces of the insulating housing 2 . These are supported in an area of the insulating housing 2 which is not weakened as much by the adjacent conductor insertion channel 3 as the section of the intermediate dividing wall 7 situated in the center region.
  • the push button 6 has a shoulder 29 a , 29 b which decreases to the width of the actuation end 21 as compared to the central portion 27 and the actuation head 22 .
  • This shoulder 29 a , 29 b forms a stop for bearing on an edge portion 30 of the bus bar 8 delimiting the connection opening 9 .
  • the width of the actuation portion 21 seen in the illustrated cross section is adapted to the width of the connection opening 9 in the bus bar 8 and at least slightly less than said width of the connection opening 9 . In this way, it is ensured that the push button 6 can dip into the connection opening 9 .
  • FIG. 5 shows a cross sectional view of the connecting terminal 1 of FIG. 2 in the state of actuation. It becomes clear that the actuation end 21 dips into the connection opening 9 of the bus bar 8 .
  • the shoulders 29 a , 29 b formed towards the actuation end 21 in the transition of the widened lateral bearing surfaces 28 a , 28 b of the central portion 27 thereby abut the edge portions 30 of the bus bar 8 , which laterally delimit the connection opening 9 . This way, the push button 6 is prevented from further depressing into the connection opening 9 .
  • FIGS. 4 and 5 further clarify that the center of the connection opening 90 does not align with the center of the actuation channel 5 .
  • a gap is present in the actuation channel 5 between the lateral wall of the insulating housing 2 of the connecting terminal 1 and the push button 6 .
  • FIG. 6 shows a sectional view of a further embodiment of a connecting terminal 1 .
  • This is similar in structure to the previously described connecting terminal 1 and in this respect only has a few modifications. In essence, therefore, reference may be made to the previous, detailed description.
  • the conductor insertion channel 3 first has a cylindrical sheath section M, which then transitions into a conically tapered section.
  • the sliding surface G is aligned in parallel with the actuation axis B.
  • the dividing wall 7 is drawn down so far from the upper plane of the bus bar 8 or from the plane which is spanned by the connection opening 9 that in the non-actuated state, the clamping leg 15 is spaced immediately adjacent to the dividing wall 7 , where appropriate, with a small gap.
  • the actuation head 22 has a lug 31 projecting in the direction of the conductor insertion channel 3 , which in the non-actuated state protrudes freely into the conically widening head portion of the actuation channel 5 .
  • the push button 6 is designed free of projections and tapers up to the actuation end 21 .
  • the clamping leg 15 exerts an actuation force F on the clamping end 21 of the push button 6 , which, as shown, is aligned at an acute angle to the sliding plane G or the actuation axis B. This acute angle amounts to less than 50°.
  • the internal angle of the direction of force F to the sliding plane G amounts to about 30°.
  • the actuation axis B is arranged offset at an angle to the conductor insertion axis L.
  • this angle is about 15°+/ ⁇ 5°.
  • Very suitable is an angle of 16°, wherein the actuation axis B is perpendicular to the plane of the bus bar 8 or to the plane spanned by means of the connection opening 9 in the bus bar 8 .
  • FIG. 7 shows the connecting terminal of FIG. 6 in the state of actuation.
  • the push button 6 is linearly displaced in the direction of the actuation axis B and along the sliding plane G in the image plane downward towards the bus bar such that the tapering actuation end 21 dips into the connection opening 9 of the bus bar 8 .
  • the clamping leg 15 of the clamping spring 11 exerts an actuation force F on the actuation end 21 , which acts at an angle of less than 50° towards the sliding plane G. Again, the inner angle is considered.
  • the force acting on the push button 6 by the clamping leg 5 is thus directed in the direction of the actuation axis B rather than transversely thereto.
  • the force direction is oriented such that it points toward the dividing wall 7 .
  • the tilting moments acting on the actuation end 21 are thus negligible. Due to the tapering actuation end 21 , which follows the direction of extension of the sliding plane G and the actuation axis B and is free of projections, such adverse tilting moments and deformation energies are avoided, which could affect the stability of the push button 6 .
  • the conductor channel wall 4 has a further end portion which follows substantially the direction of extension of the conductor channel wall 4 in the sheath receiving section M. This end portion then merges into the transition of the connection opening 9 for connecting the bus bar 8 and serves therefore as an extension of the clamping wall 10 c.
  • the dividing wall 7 is rectilinear towards the bus bar 8 towards the actuation opening in the area of the guide section for the push button 6 .
  • the dividing wall 7 has a nonuniform cross section in this guide section and forms a wall section below the sheath section M, which conically tapers the conductor insertion channel 3 . Adjoining this conical tapering of the conductor insertion channel 3 , in the mouth towards the connection opening 9 in the bus bar 8 , the end portion of the conductor insertion channel 3 merges into a cylindrical section or a section with a constant cross section.
  • FIG. 8 shows a cross sectional view of a detail of an embodiment of the connecting terminal 1 in the area of the actuation head 22 of the push button 22 . It is clear that the inside wall 40 of the actuation channel 5 toward the actuation opening situated opposite the dividing wall 7 is formed inclined at the top end of the actuation channel 5 in the direction of the dividing wall 7 . In the illustrated return of the push button 6 , this leads to a tilting of the push button 6 in the direction of the dividing wall 7 and the conductor insertion channel 3 . Thus, the gap or slot seen in FIGS. 3 and 4 is at least largely closed between the dividing wall 7 and the actuation head 22 . The possible penetration of dirt and/or foreign particles is thus avoided, and the visual appearance is improved.
  • the actuation head 22 is somewhat thicker in the width direction than over the remaining portion.
  • the actuation opening of the actuation channel 5 in the width direction can be filled out as much as possible except for a small lateral gap.
  • the push button 6 is aligned slightly tilted in the series-line up direction of the terminal block on a mounting rail, i.e., in the direction of the side walls.
  • the same symmetrical push button 6 can be used reversibly, and a uniform connection diagram is achieved.
  • FIG. 9 shows a cross sectional view of the detail of FIG. 8 in section A-A. It can be seen that the actuation head 22 fills the actuation channel down to a small remaining gap. It is also clear that a side wall of the conductor insertion channel is opened laterally. In this area, an insulating sheath of an electrical conductor to be clamped can be dipped, which assumes the insulating function of the side wall. In this way, the connecting terminal, for example in the form of a terminal block, can be made narrower.
  • FIG. 10 shows a cross sectional view of the detail of FIG. 8 in section B-B. It is clear that the push button 6 is markedly narrower in this section than in the area of the actuation head 22 .
  • the conductor insertion opening 3 is also laterally opened in this area and is circumferentially closed only with the insulating sheath of the electrical conductor to be clamped or with the side wall of an adjacently arranged terminal block.
  • FIG. 11 shows a cross sectional view of the detail from FIG. 8 in section C-C.
  • the push button 6 is located on the clamping leg 15 of the clamping spring so it can slide down along the clamping leg 15 towards the clamping edge when depressed.
  • the conductor insertion opening 3 is tapered in this portion of the section and circumferentially closed by the insulating housing 2 . In this part of the section, the stripped end of an electrical conductor to be clamped is received.
  • FIGS. 12 and 13 show a perspective view of the front side and back side of the push button of the connecting terminal of FIG. 7 .
  • the push button 6 is widened in the area of the lateral bearing surfaces 28 a , 28 b . At least in the state of actuation of the push button 6 , this width protrudes beyond the width or the diameter of the conductor insertion channel 3 , so that the acting spring forces can be absorbed by the thicker lateral sidewalls. This is indicated in FIG. 11 .
  • the dividing wall 7 can thereby be made thinner in the center area, which results in an overall smaller design of the connecting terminal.
  • the push button 6 has groove-like recesses 32 in the area of the bearing surfaces 28 a , 28 b . These can be different for different variants of the push button 6 .
  • the groove-like recesses 32 are thus encodings that can be detected using automated optical sensing and can be used for an automated assembly.
  • FIG. 14 shows a perspective view of the connecting terminal 1 from FIG. 8 obliquely from below. It is clear that the laterally opened side wall of the conductor insertion channel 3 is filled out by the insulating sheath of an electrical conductor 33 to be clamped. It can further be seen that the push button rests on the clamping leg 15 of the clamping spring 11 . The bearing surfaces protrude laterally and are applied to the insulating housing 2 .
